Amsoil provides great quality products, always recommend !

Great oil! Great service! I can always depend on the delivery to be quick and accurate.

I've been using amsoil for a couple years now. After I blew my original motor in my 2013 Dodge Ram 1500 Sport pickup. I purchased a new motor and began using Amsoil because the shop that I took my truck to for the removal and installation of new engine provided Amsoil so I said let's use the Amsoil it reminded me of home. Quite honestly watching John Gillespie fishing show is what got me interested in Amsoil he was always promoting Amsoil on his fishing show. Anywho I now reside in Tower minnesota. I'm on my fourth oil change of Amsoil oil synthetic 5w-30. The first couple of oil changes was with a 5000 mile synthetic oil. The last two oil changes have been with 25,000 Mi 5W30 oil synthetic. Honestly I change the oil at 10,000 a little over 10,000. I've noticed a little bit better fuel mileage but definitely more power in my motor so much smoother after an oil change. I will continue to use Amsoil for the life of this motor. Thank you Amsoil for a great product. Sincerely Joey Johnson

Just started using this oil in my 19 Silverado. Hope to beat the AFM that ruins one of the best engines made.

I have 2 vehicle that I use Amsoil Signature Series 0W-20. One has 216k and the other 105k and neither have had any engine issues. I guess the proof shows for itself. No plans on changing.

I have been using Amsoil oil, filters, engine flush, grease, and other products for many years. I have been extremely satisfied with their products and highly recommend them. The only issue I have had and it is recent, they have been out of their Amsoil oil filters for both of my vehicles. They offer the standard Wix filter but I am buying the Wix XP now from Amazon.

I've been hoping for this viscosity for a year or two and you delivered. But a moonshiner would be shot if he sold his corn liquor in quart jugs. (If there is such a critter). This product in warmer climates should be a good to great seller. Maybe cooler areas too? Anyway Amsoil needs to get this into a gallon jug so I can stop storing my drain oil in milk jugs. (Cleaned out of course)

Top quality product

Keeps turbo quiet runs smooth

I’ve just recently started a job as a medical courier. I was unaware of the amount of miles that I would be putting on my truck. I’ve used AMSOIL in the past but now realize that I need the best oil $$ can buy to care for my truck. Every thing I’ve read about AMSOIL from independent testing says that they are the best and truly a full synthetic oil. Pennsoil ultimate would be second. All the rest Mobil 1, Castro and valvoline are just marketing.

Oil pours well from the bottle into the engine.

I’ve been using AMSOIL in all my vehicles for about 30 years and have never any issues with the engines, so as far as I’m concerned, it does an excellent job.

I used this for my Evo highly recommend it

I use this oil for my 2008 Nissan 350Z.

Second round of using in my wife’s Caddy CT6. The bundle option was very convenient. I’ll begin using in my Silverado soon. Old Product looked great coming out of pan (like we could’ve gotten another 3k miles out of it).

AMSOIL stands out for its quality and reliability. It’s a premium product that delivers exactly what it promises. If you want better engine protection and longer oil life, I highly recommend AMSOIL.

No matter what product I use of ams oil, they always deliver and never let me down.

My engine sounds fantastic when this oil is in it and the metal parts per million are very low after an oil change using this oil.

I've used this oil for a few years in all four of my family's Subarus. All have the same 2.5L H4 engine, are 2014, 2015 models with between 80 and 140K miles. I change twice a year at around 5K miles. I know the Amsoil folks claim this oil is good for lots more miles, but we drive short trips and so I change it more often. I add less than 1 qt. between changes, so oil consumption is low for such high mile engines. All engines start, run and drive very smoothly and quietly. I definitely recommend this product!
